Cylinder 5 misfire help

Hello all! I just got my Liberty back from the body shop and the check engine light was on. I had them check it and they said it was a cylinder 5 misfire code. They told me to not worry about it, they said it's probably just from being moved short distances in and out of the garage so many times. But I've been driving it for a day now and it still has the check engine light on and at idle it stutters, and shakes. So there is obviously something still wrong with it. I need help fixing the problem as cheaply as possible since I am a broke college student. Any input would be greatly appreciated!!

Def need the mileage. Prob just need plugs and possibly coils if that doesn't fix it.
Spark plugs every 25-30K.

OME lift
Hypertech Max Energy

It's a 2009 and it has 55k miles. I don't know when the plugs where changed last, I bought the Liberty off of my grandfather who got his license taken away.

Plugs are due every 30,000 miles,you are probably due for the second time around.Make sure you use original NGK copper core plugs,They are the cheapest and are the one that will work best.Also you may also want to check your air filter to check if its not full of dirt or débris from the body shop.

Lifter would usually cause a loud clacking noise.

What tools do you have ? And I'm sure we all can help you get up and going cheap. RENE65 yes I agree with you 100% and I have seen them do both.

Thank you all for your input!! After many phone calls and arguments I got the body shop to cut me a check to go to the dealer and get the problem fixed! This forum and it's users are absolutely fantastic!! I plan to post any modifications that I do! But don't count on a lot, money is tight!

I'd bet it's a ignition coil or plug.
